No. 13/526,465, filed on Jun. 18, 2012, and claims priority from and the benefit of Korean Patent Application No. 10-2011-0058975, filed on Jun. 17, 2011, each of which is hereby incorporated by reference for all purposes as if fully set forth herein.

BACKGROUND OF THE INVENTION

1. Field of the Invention

Exemplary embodiments of the present invention relate to a method, a system, and a computer-readable recording medium for providing a ranking of a game group, in which the group is created among users who have joined a game service as a member on a client terminal device, and the ranking is provided for the created group.

2. Discussion of the Background

As the performance of recently released smart phones is enhanced, users may move from general cellular phones to smart phones. A smart phone is an intelligent cellular phone having computer support functions such as, personal digital assistant (PDA) functions, Internet functions, and moving image playback functions, while still providing original functions of the cellular phone. The smart phone may have a variety of input methods and a touch screen to provide a convenient interface for use. In addition, the smart phone may be connected to the Internet and other computers with the support of wireless Internet functions so as to perform functions, such as e-mail, web browsing, facsimile, banking, and/or playing a game. The smart phone is equipped with a standardized operating system (OS) or a dedicated operating system to perform a variety of functions.

Since a variety of functions can be implemented through various client terminal devices such as the smart phone, a variety of dedicated application programs and contents operating within the client terminal device have been developed. In addition, as the functions for client terminal devices are improved, a large number of mobile games that users can enjoy in an environment similar to the web have been developed. Numerous network games have been developed to allow users who have connected to a network through client terminal devices to play the same game while being connected with the network. When a user is playing a game, a game client is generally mounted on the client terminal device and connected to a game server through a wired or wireless communication network, so as to execute the game on the client terminal device.

Most games record game points of each user and show a ranking of the game points. However, since a conventional ranking service provided for a game shows a general ranking of the game users, the general rankings generally do not provide information that motivates the game users, and the rankings are not shown in a variety of ways. Accordingly, there is a limitation in providing meaningful information.

The above information disclosed in this background section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does not form any part of the prior art nor what the prior art may suggest to a person of ordinary skill in the art.

Hereinafter, exemplary embodiments of the invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily understand the invention.

A game service platform manages information on each game in association with a plurality of games, provides a function for creating a group, and calculates and provides a ranking of each group. A method for providing a ranking may be implemented within each game program without separately installing the game service platform in a smart phone, and the method may be implemented on the game service platform to create a group, provide a ranking of the created group, and provide an integrated ranking of the plurality of games.

Creating a Group

FIG. 1 is a view showing how a user may create a group according to exemplary embodiments of the present invention. Referring to FIG. 1, a game service user may register game friends by a variety of methods in relation to a game service. The registration methods include, but are not limited to, automatically adding a friend from the user's address book, automatically adding a social network service (SNS) friend, searching for and adding a person who registered the game service user as a friend, searching for and adding a friend using an identity (ID)/nickname, or adding a person from a list provided through a user information window or recommendation of non-acquaintances. The user may create a group within the registered game friends (e.g., acquaintances) or among all game service users (e.g., all the users without distinguishing acquaintances and non-acquaintances).

When a group is created with respect to all the game service users, tags (e.g., Orange County working mom, Stunning Beauty K, Drama Buff, or NHN) are designated to the group, and the group may be created according to each of the tags. If the group is created in this way, some of all the service users may join the group, thereby creating the group.

If a specific group is created within game friends or among all the game service users, a ranking of a user within the group or a ranking among the groups is calculated, and information on the calculated ranking may be provided to each service user within each game program, or preferably through the game service platform which will be described later.

Game Service Platform

FIG. 2 is a view showing a game service platform according to exemplary embodiments of the present invention. Referring to FIG. 2, the game service platform supporting the ranking providing system may allow a user to easily create a group by registering a game friend or tag, and may provide a basis for easily joining a group and providing a ranking of each group.

For example, a user may register his or her acquaintances as game friends and may create a small group within the corresponding game friends, or may create a group by setting a tag and form a group with respect to all game service members (non-acquaintances). In addition, a ranking within a social network service (SNS) group which the user has joined or a ranking among the groups may be provided.

In addition, effective ranking information may be provided through the interconnection between an individual game and the game service platform. For example, structural flexibility may be secured by providing ranking information of an individual game within the game and/or switching the ranking information to a screen of the game service platform using a ranking interface customized within the game.

Accordingly, meaningful rankings within a created game group may be provided by providing the ranking information through the game service platform. A sense of belonging and solidarity of a community may be obtained by comparing the rankings among the groups.

Hereinafter, a system and detailed components thereof according to exemplary embodiments of the present invention will be described with reference to FIGS. 3 and 4, and procedures of recommending a friend and executing a game according to exemplary embodiments of the present invention will be described in detail with reference to FIGS. 5, 6, 7, and 8.

For example, if the user selects a ranking inquiry function for a specific group that the user has joined from a game service platform screen after a game service platform application is installed and executed in the client terminal 320, the client application may request a corresponding inquiry of ranking from the game service platform server 301. Then, the game service platform server 301 may inquire group information stored in the group information database 455 through the group ranking calculation unit 433 or the within-group ranking calculation unit 434, calculate a ranking within the corresponding group and a ranking of each group, and transmit the calculated result to the client terminal 320. The client terminal 320 may subsequently confirm the result of the inquiry. Accordingly, a variety of functions may be performed at a server 410, at a client terminal 320, at both the server 410 and the client terminal 320.

Database Server

The database server 306 may include a member information database 451, a game information database 452, a friend information database 453, a record information database 454, and a group information database 455, and may further include other databases needed for providing the game service platform.

The member information database 451 stores a variety of information on members who have joined as a service member or a game member through the game service platform. For example, the member information may include personal identification information of a corresponding member, a picture needed for profile information, a nickname, an avatar, recently played games, installed games, information on a result or a record of each game, ranking information, information on challenging tasks, information on joined SNSs, information on settings of personal information exposure, and information on settings of automatic login.

The game information database 452 stores information on a plurality of games associated with the game service platform server 301. For example, the game information may include information on software installed for each game, information on firm-up software, information on a version of each game, information on a record of each game, information on a challenging task of each game, information on a channel connecting to the game service platform server 301, and information on a member who has joined a corresponding game.

The friend information database 453 stores a variety of information related to SNS game friends registered by a user as a friend or automatically registered in association with a SNS server. For example, the friend information may include information on an ID and a nickname of a registered friend, information on a registration channel, and information on blocked friends.

The record information database 454 may store a variety of records according to a result of a game played by each member. For example, the records information may include a number of rounds played in each game, a score of a member in each game, and a score of a challenging task.

The group information database 455 may include information on a group created through the group creation unit 431 (e.g., tag information of a group, information on a group creator, and information on qualifications for joining a group) and information on a group member who joined through the group join processing unit 432.

Overall Service Procedure

FIG. 5 is a flowchart illustrating a method of providing a game according to exemplary embodiments of the present invention. First, a client terminal 320 (e.g., a smart phone) may download and install a game service platform software S/W (S501), and drive the installed game service platform (S502). Then, the user may join the game service platform as a member and log into the game service platform (S503).

The user may then create a group using several methods (S504). For example, the user may create a group of friends by adding friends, may create a group of SNS friends registered via user account authentication of an SNS service that the user has joined, and/or may create a new group by registering a tag. In some cases, if the user would not like to create a new group, the user may inquire about a previously-registered group using a tag and join the group (S505). In some cases, in addition to creating a new group, the user may inquire about a previously-registered group using a tag and join the group (S505)

It should be understood that the user may create or join one or more groups in S504 and S505. The user may create a group by adding friends, create a SNS friend group, and/or create a new group by registering a tag in any order or in parallel. To create a friend group by adding friends, a new group can be created using a method of selecting or adding some or all of the friends registered by the user. To create a SNS friend group, a new group can be created using a method of selecting or adding some or all of the game service members registered as a friend in a SNS service that the user has joined. To create a new group by registering a tag, a new group can be created using a method of inputting a tag mapped to a new group created by the user. If one or more groups are created, rankings of a corresponding group can be inquired through the game service platform, and a ranking within the group and ranking information of each group may be outputted through the game service platform as a result of the inquiry (S506).

Hereinafter, methods of creating and joining a group and inquiring about rankings of the group according to exemplary embodiments of the present invention will be described with reference to FIGS. 6, 7, and 8.

Procedure of Creating a Group

A group which provides ranking information may be created using a variety of methods. A group of friends may be registered according to a variety of methods (e.g., friends registered in an address book, friends registered in a SNS). A group may be created including the registered friends, or a small group can be separately created by selecting some of the friends from the registered group of friends.

As shown in FIG. 6, a user may create a new group by registering a tag, and all the game service members can be registered as a member of the group. FIG. 6 is a flowchart illustrating a method of creating a group according to exemplary embodiments of the present invention. If a group creation menu is selected through the game service platform (S601), a new group is created by inputting a group name or a tag (S602). If the group name or the tag is a word already registered (S603), another group name or tag is inputted. This step may be repeated until a name that is not registered is input.

When an inputted group name is not registered, qualifications (e.g., an age, a region, a game ranking) for joining the group may be input (S604). Accordingly, creation of the group is completed (S605).

Although exemplary embodiments described above describe that a group may be created by inputting a group name or a tag, in some cases, one or more tags may additionally be set after the group name is set. For example, after three tags are set to one group name, a user may search for a corresponding group by inputting the registered group name or tag. When a group is searched using a tag, a plurality of groups including the same tag can be obtained as a result of the search. For example, if a person living in Orange County searches for a group by searching for ‘Orange County’ as a tag, a plurality of groups (e.g., ‘Orange County working mom’, ‘Orange County NHN’) including ‘Orange County’ as a tag can be searched.

Procedure of Joining a Group

FIG. 7 is a flowchart illustrating a method of joining a group according to exemplary embodiments of the present invention. As shown in FIG. 7, registered groups may be searched for by entering a group name through the game service platform (S701). According to a search result of the entered group name, a list of searched groups may be displayed (S702). The game service platform may determine if the user has selected a specific group to join from the list (S703). If a group is not selected, the method for joining a searched group may end.

If a group is selected, a group join request signal may be transmitted to the group join processing unit 432 of the group ranking management unit 430 included in the game service platform server 301 of the service server 300, and the group join processing unit 432 may determine whether or not the user requesting to join the group meets the qualifications for joining the group based on the group information database 455 (S704). If the user meets the qualifications as a result of the determination (S705), the process of joining the group for the user may, in some cases, be complete (S707).

In some cases, the user may be approved immediately to join the group if the user meets the qualifications as described above, but, in some cases, the service server 300 or the creator of the group may need to approve the user's request to join the group (S706).

Procedure of Inquiring about a Group Ranking

FIG. 8 is a flowchart illustrating a procedure of inquiring about a group ranking according to exemplary embodiments of the present invention. As shown in FIG. 8, if the user selects a group ranking inquiry through the game service platform (S801), a tag input window for the group ranking inquiry is provided, as shown in FIG. 10. A joined group may be searched for or inquired about, or a new group may be created with other members as described in FIG. 5. For example, a group may be inquired about by inputting a tag name into the tag input window (S802). If ranking inquiry for a group corresponding to the input tag name is requested from the service server 300 (S803), the group ranking management module 430 of the service server 300 may confirm a list of members of the group through the group information database 455, determine whether a plurality of game services associated with the game service platform is installed in terminals of the members of the joined or created game group, and read scores of each member from the record information database 454. The client terminal 320 may receive, from the service server 300, information regarding the results of the determination of whether the plurality of game services associated with the game service platform is installed in terminals of the members of the group. A list of the plurality of game services installed in terminals of other members of the group may be displayed in the client terminal 320, and the user may select at least one of the game services that may be of interest to the user.

Then, a group score may be calculated based on a predetermined method (e.g., addition of individual game scores or activity scores of each member, or an average score of each member) (S805). Accordingly, a ranking of the user within the group may be calculated (S806), and a ranking among the groups may be calculated by comparing the calculated group score with scores of other groups (S807). For example, in some cases, if the user selects one of the game services displayed on the client terminal 320, ranking information of the user with respect to other members having installed the game service selected by the user may be calculated.

The calculated ranking result may be displayed through the game service platform of the client terminal 320 (e.g., smart phone) of the user who has requested the group ranking inquiry (S808).

FIG. 9 is a view showing an information storage table 900 for providing a group ranking for each user according to exemplary embodiments of the present invention. Referring to FIG. 9, in order to provide a ranking of each group and a ranking among the groups according to exemplary embodiments of the present invention, it is preferable to collect and store a variety of information related to the group for each user.

For example, as shown in FIG. 9, information such as a user ID 910, a nickname 920, groups (tags) created by the user 930, joined groups (tags) 940, registered friends 950, joined SNSs 960, and user's scores 970 can be stored and managed in each database.

Example of Implementing a Service

FIG. 10 is a view showing a screen of a smart phone 320. The screen displays a group ranking inquiry according to exemplary embodiments of the present invention. Referring to FIG. 10, if the group ranking of the game ranking menu is selected on the game service platform driven at the user's smart phone, a tag input window is provided for inputting a group name or a tag. If a group name or a tag is inputted as a keyword through the tag input window, a ranking of a group which sets the inputted keyword as a group name or a tag can be inquired about.

FIG. 11 is a view showing a screen of a smart phone 320 displaying a result of a group ranking inquiry according to exemplary embodiments of the present invention. Referring to FIG. 11, a daily or overall ranking of a group are provided as a result of the group ranking inquiry of FIG. 10, and ranking information of the user in the group can be confirmed. For example, as shown in the FIG. 11, if the joined group is ‘NHN’, the user's ranking information 1100 in the ‘NHN’ group and a ranking of the ‘NHN’ group 1110 compared with those of the other groups can be provided.

FIG. 12 is a view showing a screen of a smart phone 320 displaying a result of a SNS friend ranking inquiry according to exemplary embodiments of the present invention. Referring to FIG. 12, ranking information within a group created by some or all of the users who have joined a SNS (of which the user is already a member) as a friend may be determined. Ranking information within a group created by the user may also be obtained. As shown in FIG. 12, if a corresponding user has joined a SNS service such as Facebook®, the user may confirm his or her ranking among the user's friends registered in the Facebook® service.

Accordingly, a sense of belonging and solidarity of a community can be strengthened by confirming rankings within a group related to the user and rankings among the groups, and not by providing conventional meaningless overall ranking information.
